Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55690, here are decompositions:
- 17 + 55673 = 55690
- 23 + 55667 = 55690
- 29 + 55661 = 55690
- 59 + 55631 = 55690
- 71 + 55619 = 55690
- 101 + 55589 = 55690
- 149 + 55541 = 55690
- 179 + 55511 = 55690
Showing the first eight; more decompositions exist.
